Code generation
Does the code do what the task asked, and is it actually right?

Synthium Agents
Coding and reasoning agents produce work a generic annotator can't judge. Our engineers assess code generation, debugging, architecture, security, reasoning, tool use and task completion — the things that decide whether an agent is trustworthy in production.

Evaluation dimensions
Eight signals we hold agents to
Every trajectory is reviewed against the signals that actually predict whether an agent is safe and useful — by people who could have written the task themselves.
Debugging
Can the agent locate and fix the real fault, not a symptom?
Repository-level reasoning
Can the agent reason across a whole codebase, not just isolated snippets?
Tool use
Are tool and function calls correct, sequenced and safe?
Task completion
Did the agent reach a finished, verifiable end state?
Architecture
Are the structure and design decisions sound under load?
Security
Does the output introduce vulnerabilities or unsafe patterns?
Failure modes
Does it recognize and surface its own failure modes and limits?
Workflow
From task to defensible report
A disciplined loop: run representative tasks, have engineers evaluate them, score against your rubric, and hand back signal you can ship on.
Tasks
We run your agent against real, representative tasks spanning the difficulty range you care about.
Expert eval
Engineers review each trajectory — code, reasoning, tool calls and outcome — not surface fluency.
Calibrated scoring
Judgments are mapped to your rubric, with reasoning attached to every score and flag.
Reports
You get per-signal breakdowns and failure modes you can act on, not a single opaque number.
Why a generalist annotator can't do this
A coding or reasoning agent fails in ways only an engineer recognizes — a subtly wrong refactor, an insecure dependency, a confident answer built on a flawed premise. Judging those outcomes is itself an engineering task. We bring the people who can do it, calibrated to your bar.
